7.35mm Italian Carcano

.7.35mm Italian Carcano

The 7.35×51mm Carcano cartridge was developed by Italy in the late 1930s as a successor to the 6.5×52mm Carcano, which had been in service since the 1890s. Intended to improve both range and terminal effectiveness, the 7.35mm used a slightly larger bullet diameter (nominally .300 caliber) and a spitzer-style projectile with an aluminum-filled tip, which was designed to tumble upon impact for greater stopping power. This innovative design reflected a shift in military doctrine toward more modern ballistics and effectiveness at combat ranges.

The Italian military adopted the cartridge officially in 1938 alongside the Fucile Modello 91/38, a shortened carbine variant of the older Carcano rifle. However, the transition was short-lived. By 1940, the logistical burden of supplying two separate calibers during wartime, combined with limited production capabilities, led the military to revert to the more established 6.5mm Carcano. As a result, rifles chambered in 7.35mm were produced in relatively small numbers and are now rare collectibles.

For reloaders, the 7.35mm Carcano presents unique challenges. Bullets of the correct diameter (.300–.301") are not widely available in commercial form, often requiring custom casting or resizing from other projectiles. Brass can be formed from 6.5mm Carcano cases or found in small batches from specialty suppliers. Due to the limited historical data and small production run, published reloading data is scarce, and any work should begin with conservative loads, especially when firing through original surplus rifles that may have seen inconsistent maintenance over the decades.

Despite its short service life, the 7.35mm Carcano remains a fascinating example of interwar cartridge development. It reflects Italy’s attempt to modernize their small arms in a rapidly changing geopolitical landscape. Enthusiasts who own and reload for this cartridge often value it for its historical significance, as well as the craftsmanship seen in many of the original rifles still in circulation.
